In this paper, an adult authentication system based on authentication certificate was designed and implemented using smartphone and near-field communication. It has three advantages. First, it achieves easy, convenient, and fast authentication by using smartphone and near-field communication. Second, it achieves extremely high security and reliability by exploiting authentication certificate. Third, it achieves extremely low risk of personal information leakage by generating and sending only virtual identification code. Finally, it has a proper legal basis by Digital Signature Act. It consists of adult authentication module, near-field communication control module, policy server module, and database server module. A prototype of the proposed system was designed and implemented, and it was verified to have correct operation.

Most people do not think seriously about the concept of time management, just to spend the precious time sheets. Regular life can sustain mental and physical health. That's why time management is an important factor in living. In the thesis, smart alarm patch is designed using a wireless communication NFC technology that gradually develop and attract attention. Due to the alarm, regular hours is helped to improve the quality of life. For this, analysis was performed using the UML in this system, linked to the smart alarm system patches and NFC technology, Java Script language, Adobe Muse CC was used embody web document and mobile content.

The PSK (Pre-shared Secret Key) based method is appropriate for the IoT environment consisting of lightweight devices since this method requires less computing time and energy than the method to configure the session key based on the public key algorithm. A fundamental prerequisite for the PSK based method is that PSK should have been configured between the communication entities safely in advance. However, in case of a small sensor or actuator, no input and output interface such as keyboard and monitor required for configuration exists, so it is more difficult to configure PSK for such lightweight devices safely in the IoT environment than the previous Internet devices. Especially, normal users lack expertise in security so they face difficulty in configuration. Therefore, the default value configured at the time of manufacturing at factories is used or the device installer configures PSK in most cases. In such case, it is a matter for consideration whether all installers and manufacturers can be trusted or not. In order to solve such problem, this paper proposes a secure bootstrapping scheme, which utilizes the NFC (Near Field Communication) as an OOB (Out-Of-Band) channel, for lightweight devices with limited resources.

As plant market grows up, client demands to increase quality, technology and to reduce construction period. Due to the vast scale of the construction site and complexity of process, plant project can have some problems of communication among the project participants, the duplication of work, errors and rework. As a result those cause more costs, delay the construction schedule and reduce productivity and quality. Therefore, real-time communication between participants and real-time sharing of information such as material, equipment and construction are required in plant project site. This research aims to propose process and develop system using NFC(Near Field Communication) technology and augmented reality technology with mobile device for plant construction site. Administrators and operators are able to work efficiently using proposed process and system which create an environment designed to share and deliver information such as material, construction information.

최근 정보통신기술의 발전으로 생활 속 사물들이 서로 네트워크를 이루며 지능적으로 변화하면서 사물인터넷이라는 개념이 주목받고 있다. 앞으로 활용될 것으로 전망되는 사물인터넷 서비스를 제공하기 위해 기존의 무선 통신 기술 중 하나인 NFC가 사용되고 있다. NFC를 이용한 사물인터넷 서비스 중 하나인 서버 클라이언트 기반 NFC 운용체계가 공격에 노출된 경우 운영체계를 이용하는 모든 사용자의 디바이스까지 공격하는 것이 가능할 것으로 판단되며, 이런 보안 위협에 대한 연구는 크게 고려되지 않는 실정이다. 따라서 본 논문에서는 서버 클라이언트 기반 NFC 운영체계에서 발생할 수 있는 보안 위협에 분석하고 그에 따른 대응 방안을 제안한다.

In this paper, a fully printed NFC tag operating at 13.56 MHz was designed and fabricated using silver nano-paste and carbon ink. The proposed NFC tag has a printed coil with an inductance of $2.74{\mu}H$ on a PI film for application to an NFC tag IC with an internal capacitance of 50 pF. Screen printing technology used in this paper has advantages such as large area printing for mass production, low cost and eco-friendly process compared to conventional PCB manufacturing process. The proposed structure consists of a circular coil implemented as a single layer using silver nano-paste and carbon ink, a jumper pattern for chip mounting between the outer edge and the center of the coil, and an insulation pattern between the coil and the jumper pattern. In order to verify the performance of the proposed NFC tag, we performed the measurements of the printing line width, thickness, line resistance, adhesion and environmental reliability, and confirmed the suitability of the NFC tag based on the full-printed manufacturing method.
